Answer:
1 2/7 ........................................
Marcia dissolved 1 kg of salt in 3 litres of water.
Bobby dissolves 2 pounds of salt in 7 pints of water
2.11 pints = 1 litre
7 pints = 7/2.11
= 3.32 litre
1 pound =0.45 kg
2 pound = o.45*2 kg
= 0.9 kg
So we find that Bobby is dissolving 0.9kg of salt in 3.32 litre of water
Marcia is dissolving 1 kg of salt in 3 litres of water.
Linear function is the other equation

Answer:
50
Step-by-step explanation:
The range is 50 because the maximum number is 90 and you subtract that from 40 which gives you 50.
90= maximum
40= minimum
90-40=50
